"Due to a remotely exploitable security hole being discovered that
effects all previous Webmin releases, version 1.070 is now available
for download from http://www.webmin.com/ and mirror sites. This
problem was reported by Cintia M. Imanishi, but fortunately there
have been no known malicious exploits of it yet. However, all users
should upgrade to 1.070 as soon as possible."

"Also available is Usermin 1.000 which fixes the exact same security
hole. It includes the same File Manager features, as well as support
for IMAP folders and an IMAP inbox in the Read Mail module."
